Could brain structure determine your politics?

Our brains may determine if we are left handed or right handed but what if we are left-wing or right-wing?

A study in the journal Current Biology finds opposing political views may be linked to differences in brain structures.

Brain scans were done on students who revealed their political views beforehand.

The "liberal" students tended to have a larger region of the brain that processes conflicting information that may make for tolerance to uncertainty.

The "conservatives" tended to have a larger part of the brain that process fear, making them better able to identify threats.

What is not clear is whether political preferences and other personality traits influences brain structure or vice versa.
